Carbon footprint of household meat consumption in China: A life-cycle-based perspective

The food industry accounts for 25% of global carbon emissions, of which animal food accounts for 57%. Therefore, the reduction of carbon emissions from meat products consumption is one of the important issues of global climate governance. This study calculates and compares the carbon footprints of major meat products in China at various stages of production and consumption and the trends of their development based on life cycle assessment and questionnaires, which will help to understand the emission characteristics and reduction potential of the food sector in China. The results show that the main stages of the life cycle and the size of the total carbon footprint of the meat category for the same unit standard exhibit the following order: beef > mutton > pork > poultry (chicken and duck) > seafood (fish and shrimp); the farming factor has a greater impact on carbon emissions, followed by transportation and a smaller impact at the meal-making stage; from 2010 to 2021, China's total meat products consumption and carbon emissions continue to increase, but the structure of meat consumption is gradually diversified and balanced, and the trend of carbon emissions shows a slowdown in growth with structural changes. Finally, based on the results of the study, this paper proposes countermeasures for meat production and consumption.
